On Tuesday, a teenage girl got pepper sprayed directly in the face while protesting outside a Trump rally in Janesville, Wisconsin.

Thousands of Trump supporters gathered for the rally on Tuesday, but when a group of protesters arrived, things got particularly heated between a 15-year-old protester and a male supporter of the GOP frontrunner.

Crowd footage of the altercation shows a teen girl with short blonde hair and glasses shouting something to a man with grey hair.

After a heated exchange, the girl appears to sock the man in the face, when a second unidentified man reaches over and sprays her with pepper spray.

According to police, the girl — identified on social media as Alex — claimed the man she appears to take a swing at had groped her. But Dan Crandall denied inappropriately touching the teen, saying that supporters had been "warned not to make contact with protesters."

In a video filmed after the incident, Crandall said the protester had been shouting "black lives matter," and got upset when supporters were shouting "all lives matter" in response.

He said:

"She challenged me, saying 'why are you at a Trump rally if you are a grown man?' And I replied that that was exactly why I was at a Trump rally - because I am a grown man and I want to make this country great again."

The teen protester was escorted out of the crowd and treated at a local hospital. Officials are currently looking for two men — one for the alleged assault and the other accused of spraying the girl's face.
